GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 744,290, dated November17, 1903.

(No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM B. OARBICK, a citizen of the United States,residing at Chicago, in the county of Cook and State of'Illinois, haveinvented certain new and useful Improvements in Gas-Burners and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relatesparticularly to means for simultaneously lightinga cluster of gasburners, and includes a supplementary or lightingburner, which projects flames laterally in various directions over themain burners, and also a pilot-light for lighting such supplementaryburner at all times.

The invention is an improvement on the invention patented by me March 3,1903, No. 721,997.

In the accompanying drawings, Figure 1 is an elevation of the burner.Fig. 2is an elevation at right angles to Fig. 1 and partly in section.

Referring specifically to the drawings, 6 indicates the main dependingsupply pipe, which extends downwardly through a tube 8. This tube ispreferably enameled or coated with some reflecting material, such asporcelain, and is supported on the pipe by a gallery 9. At 10areindicated the main burners, forming a cluster around the saidreflectingtube 8 and supplied through the main cock 11. Above said cooka branch pipe 12 is united .to the main supply-pipe, and this branchpipe supplies gas to a secondary or lighting tube 13 and a pilot tube orburner for the latter, (indicated at 14.) These tubes pass within thereflecting-tube 8 through a hole in the gallery. The pilot-light at 14:at the end of the tube 14 is within the tube 8, so that the latter actsas a protector for the pilot-light. The tube 13, however, projects abovethe top of the tube 8 and is provided with holes or nipples 13*, whichproject laterally in direction and number, according to the number ofmain burners in the cluster.

The branch pipe supplyinggas to the supplemental burner and thepilot-light is controlled by a cock 15, which has the usual by-passsupplying the pilot-light at all times. When the cock is open, it allowsgas to pass into the tube 13, and thusto the supplemental burner 13 butthe cock is normally closed by a spring 16. Pull-chains to open andclose the main cock are indicated at 17 and 18, respectively. The formerhas a branch chain 17 to the cook 15 of the by-pass and between thejunction of the chains and the main cock has a spring 19.

The operation of the device is as follows:

' Gas is constantly supplied through the main and branch pipes to thepilot-light, and when it is desired to light the cluster the chain 17 ispulled. This first turns on the gas to the burners of the cluster.Further pull causes the spring 19 to yield and the branch chain pullsopen the cock of the branch pipe, as indicated in dotted lines in Fig.2. This turns on the gas to the supplemental burners 13*, which projectflames laterally over the tops of the main burners 10, thereby ignitingthe same. When the pull-chain 17 is released, the spring 16 closes thecook 15 in the branch pipe and puts out the flames at 13?, allowing,however, the pilot-light to remain burning through the by-pass.

It will be seen that by this device it is unnecessary to have a pilot orlighter for each burner; but the whole cluster may be lightedsimultaneously by means of one pilot-light. A saving of fittings is thusefiected, as well as a saving of gas.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a cluster of burners, of an independent burnerbetween the same, a pilot-light for the independent burner, avalve-controlling gas-supply to all of said cluster, and avalve-controlling gas-supply to the independent burner and pilot-light.

2. The combination with a main supplypipe and a cluster of burners, anda valve in the pipe controlling the gas-supply to the burners, of abranch pipe, an independent burner and its pilot-light supplied thereby,said independent burner having laterally-directed nipples the flamesfrom which are in the pipes, and a chain connected to said 10 l valvesto operate the same.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM B. CA RRICK.
